Introduction:We have all seen a
burning candle or burning wood. Burning is a chemical reaction
between the burning object and the oxygen gas. Burning is the
most well known chemical reaction that creates heat energy. Of
course not all chemical reactions create energy as much as
burning. Most heat producing chemical reactions may have no
flame at all.

In this project we will research the
chemical reactions that produce or require energy. We will also attempt
to find a general rule that helps us determine if a chemical reaction
will produce or absorb energy.

Project
description
During this project you perform varieties of experiments to determine
which chemical reactions absorb energy and which chemical reactions produce
energy.
